Public bug reported:
When logged into an iSCSI node (isciadm -m -node -l) my laptop won't
suspend to ram anymore.
"dmesg -T" after a failed suspend gives
[Mo Nov 4 13:22:54 2019] Suspending console(s) (use no_console_suspend to
debug)

Here sdb is a device I connected to using open-iscsi. The partition on
it is also mounted.
When I open the lid again, the login screen will usually show up, though
I had cases where the system would completely hang, the screen would
stay black and I had to reboot the whole thing.
"lsb_release" -rd gives
